I'm getting ready to install a fully modded JDM h22a in my '94 prelude (see list below) (no internal work). I am going with an NX 75 shot as well. Do you all think I can break into the 12's in the 1/4? If not, then why? Do you all think traction would be a problem? If so, whats a cure? I'm just trying to figure out all the details while its still in process. Thanks. Later.

traction will absolutely be a problem unless your running drag radials it will be difficult to keep the power to the ground... speaking of which. what type of clutch set up are you going to use?
EDIT: the LSD will help but id still get drag tires
Well, I was going to go with the stock clutch. I thought that I might be able to slip it easier than an aftermarket and save on some wheel spin.
I was going to go with ES motor mount as well. I heard they helped with hookup, but then again, I didn't want the vibration at idle. Later.
The reason you wont break 12s is cause you wont make enough power.....you can hit a 13.5 if you can drive.....most guys hit 13.7ish with a 75 and you may get another tenth or 2 witht he JDM, but without more juice it isnt gonna happen.....100 shot DP, maybe.....you will need a clutch too....stock clutch is useless with 250whp.........
Yeah, you can hit 12s with a 75 shot. You'll have to be on BFG drag radials though. Also a CF hood, CF trunk, light racing seats, etc would help alot. I need to shave .6 seconds off to get 12s and I could still run 13.2s with my current setup if I was cutting 2.0 60's.
Also your stock clutch won't hold well enough to get that power to the ground. My exedy organic didn't hold well enough either.
I'd suggest that you get an SMSP header, 2.5" mandrel bent exhaust piping, slap some canister on the end, tune the car w/ the VAFC, and then practice with nitrous and drag radials until you are in the low 13s. Then mess with the PnP and all of that other stuff.

I disagree... I think it's possible to hit 12s with the setup listed, considering Jon (preluderacer023) hit a 13.9 with just a Jdm h22 and minor bolt-ons, and old tires ( I think). Traction WILL be difficult, but it's still possible.

Its too hard to speculate possibilities.....without some wieght loss or a slurry of other tricks I dont think it will happen....and certainly not without some really good tires......J10sh had slicks on a track with VHT i think? Maybe it could happen....but Ill believe it when i see it......I still think that it would be easiest to turn up the juice vs. pulling a bunch of other tricks......
Besides he said can you hit 12s with the setup he has listed....to that I stick with my "no" answer.....
I say a prelude built with 10:1 CR, st2 cams, headwork and a 125 DP of NX and he hit 12.6 Si it isnt impossible.....He would be really close to a 12.9 with a 75....and he did that on street tires........
Yup That's what the track probably uses. it was the same for everyone.
A little advice for getting your best times....
DONOT go to the night races or the dedicated "import days"
go on a normal bracket racing day when the faster cars are there. The track is treated MUCH MUCH more and traction improves immensly.
Just a tip from your uncle J
yep, a lot of cars with street tires are bad news. They peel the rubber up, and any VHT that might be on top of the rubber. However I would have to say when there is a big race (IE nitro cars, pro mods etc...) the track is incredible. However street tires will still probably suck.
Thanks for the input. Everything is finished on the engine and I have all the parts. I'm just putting it back together now. I'll probably do the install next month. So... it'll probabaly be Spring before I can get any numbers. I'll let you all know. Later.
